Bad

Liked: Extremely noisy and bad smell coming from the bathroom.
Disliked: We had a private bathroom that smelt horrible of sewage.

Tired and dated

Liked: Decent location away from the main city but easy to use public transport
Disliked: The room was very dated and old. The bed was literally a plank of wood with a thin pad for a mattress. No mirror except for a tiny one in the bathroom.

Passable

Try to avoid if not...

Disliked: It was dirty, the floor was dusty everywhere and under furniture etc. it looked like never cleaned.We had a room in the 5th floor without elevator. I usually don't mind to climb some stairs, but if it's 5 floors it should say in the description.The hose from the AC just hangs loosely in the shower.The mattresses wear like 5cm thin on a hard frame.The roof windows had not shutters and was directly over the bed.I'm in Prague regularly and for the price you can get way better accommodations (picked this for the area because of an event this time).Also the name "pension" is misleading, I'd expect a small bed and breakfast style housing, but this is several tenement blocks with 5+ floors. Our entry/block/ was in the street around the corner from the block with the reception.

Passable

Poor

Disliked: Very hard beds, couldn't sleep properly.

Not recommend! Please, keep away...

Liked: I didn’t like anything. This is outright fraud: when booking, we were offered four room options with nice interiors. Upon arrival, it turned out that the room was a complete dump. The hotel staff refused to help and claimed that it was just our perception, insisting that all rooms look exactly like the photos.
Disliked: The room we received was in a terrible condition. The floor was dirty, with hair on it, and there were visible stains on the walls, table, and wall panels. The bathroom was in such a dreadful state that I was afraid to even take a shower or use the toilet: there were streaks and signs of use everywhere with no apparent cleaning. The smell from the bathroom was unbearable, like a public urinal. I had real concerns about contracting a fungus or something even worse.The furniture in the room looked like it was taken from a dumpster: it was broken, marked with ink, covered in dust and grime both inside and out. The room resembled a homeless shelter.The noise levels in the room were so bad that we could hear absolutely everything happening on every floor of the hotel. Drunk people were yelling and disrupting our sleep, but the hotel staff did nothing to address the situation. Additionally, dogs were barking, and as a result, we only managed to sleep for an hour and a half to two hours that night.
